Insects, earthworms, fungi and bacteria form the key decomposers of the Savanna biome. Decomposers are organisms that help to break down organic matter, making nutrients available in the ecosystem.Continue Reading
The Savanna biome is characterized by a rolling grassland, with isolated trees and lots of shrubs. Also known as tropical grasslands, savannas do not receive as much rainfall as tropical forests but they receive more rainfall than deserts. The climate is typically divided into two, a long dry season and a short but very wet season. Insects, earthworms, fungi and bacteria contribute as decomposers in various ways.
Some of the major insects that help decompose include locusts, flies and beetles. Termites are also a major decomposer. They feed on dead leaves and help aerate the soil by their movement.
Despite the drier climate some species of earthworm are also capable of surviving in a Savanna. They feed on organic matter, breaking it down to simpler compounds.
Although not as common as in more humid biomes, fungi also play a part in decomposing organic matter. Common examples of fungi found in the Savanna include Artist Conks (ganoderma applanatum) and Dryad's Saddle (polyporous squamosus).
Lastly, bacteria are the major decomposers in the Savannah biome. The warm temperature allows them to flourish.Learn more about Biology
Decomposers that live in a desert include fungi, slugs, snails, bacteria and worms. The decomposers are needed to eat dead things.Full Answer >
One of the only decomposers that is able to survive in the desert is bacteria because they are tiny and can survive in the air. Other decomposers, such as millipedes, earth worms and beetles, also live in the desert, but they have a difficult time surviving because they depend on moist areas.Full Answer >
Fungi, worms, bacteria, snails and slugs are all types of decomposers. Decomposers get the nutrients they need by eating dead and decaying materials. These organisms keep ecosystems healthy by ensuring plants get the nutrients they need to survive.Full Answer >
Decomposers include certain types of bacteria, worms, slugs, snails and fungi. All of these organisms break down or eat dead or decomposing organisms to help carry out the process of decomposition. They are the last step in the food chain, which recycles nutrients and breaks down wastes and organic matter in the ecosystem.Full Answer >
